Zelda Williams and Zachary Williams strike a pose together on the red carpet while attending the grand opening of SAG-AFTRA Foundation’s Robin Williams Center For Actors, Broadcasters And Recording Artists on Wednesday evening (October 5) in New York City.

“There was a look he had that used to make me laugh, because I knew he was gone,” Crystal said during the panel (via Deadline). “He knew what he was doing. He was an artist,” Whoopi added. “But he could exhaust you. We would both say ‘Just stop. Oh my God, stop!’”

The opening promoted a $16 million capital campaign that will include $6 million for the center and $10 million for the foundation’s endowment.
